One of the key figures named in the unverified anti-Trump dossier has delivered a point-by-point rebuttal shooting down more than a dozen allegations contained in its pages.

Fox News obtained a letter to the House Intelligence Committee sent Aug. 14 by the attorney representing Michael Cohen, who has served as President Trump’s personal attorney. In it, he discredits the 35-page dossier, noting that without the “sensational allegations” contained in the document, Cohen “would not be involved” in the committee’s Russia probe.

“We have not uncovered a single document that would in any way corroborate the Dossier’s allegations regarding Mr. Cohen, nor do we believe that any such document exists,” Cohen’s attorney, Stephen Ryan, wrote in the letter.

Cohen’s name has been in headlines this week after an email surfaced in which he wrote to Russian President Vladimir Putin’s press secretary about a possible “Trump Tower” in Moscow.

The dossier is a separate issue, and is known more for the salacious and unfounded allegations made against Trump. But Cohen was also named, and the letter said he “vehemently denies” all allegations, calling them “totally false.” The letter noted that based on Cohen’s “proffered responses” to the allegations, they did not believe an interview or testimony with the committee was “warranted.”

The first allegation Ryan rejected was that Cohen had “secret meeting/s with Kremlin officials in August 2016” in Prague, stating that Cohen had “never traveled to Prague, Czech Republic, as evidenced by his passport” and “did not participate in meetings with Kremlin officials in Prague in August 2016.” When the dossier was first published by Buzzfeed in January, Cohen tweeted “I have never been to Prague in my life. #fakenews.”
